Abstract: The present disclosure provides a CPAP mask with side ports for providing continuous positively pressurized air to a patient. The CPAP mask includes a mask body, a plurality of strap holders, and a cushion seal. The mask body includes a left side wall, a left port, a front face, a right side wall, and a right port. In addition, the left side wall has a first through-hole. Further, the left port is on the left side wall. Furthermore, the front face of the CPAP mask is a transparent member. Moreover, the right side wall has a second through-hole. Also, the right port is on the right side wall. Also, the plurality of strap holders is on the left side wall and the right side wall.

Abstract: The present invention provides a process for in-situ preparation of metal oxide(s) comprising the step of precipitating a metal salt solution with Fehling's reagent B and glucose at a suitable temperature. The metal oxide(s) prepared according to the present invention can be used for diverse applications including their utility as catalyst(s) in one or more reactions. The present invention further provides a highly selective bi-functional hybrid catalyst for direct conversion of syn-gas to dimethyl ether (DME) and methods of preparation thereof. The one or more metal oxide(s) can be directly obtained from the metal precursors following the method(s) of the present invention instead of metal hydroxides as in conventional known methods, thereby eliminating the necessity of high temperature calcination step(s) and rigorous reduction procedure(s).
